If you want a second opinion go to Christ Hospital in Cincinnati. That's where I used to go for my mammograms and biopsy. I really liked the atmosphere and consideration the staff gave me.

Wherever you go do it soon. Waiting will only create a "what if" situation in your mind and cause you stress.

I had sterotactic biopsies and they are pretty simple. So simple that they are not worth the stress of waiting.

I doubt if you'll find a "conservative approach". Dr's have to take a "worst case scenario" approach due to fear of lawsuits.
